NVR image size on TV screen


Here you see 3 images, 2 of them are shown from the TV screen. One of them has a smaller window for the image. The other is the larger full sized image. QUESTION… How do I make the smaller image the same as the larger one? These are attatched through a AV receiver on 2 different HDMI inputs going to 1 TV screen. The smaller image is from a “Funlux” NVR and the larger one is from a “Zmodo” NVR. The 3rd pic shows both NVRs. Where in the settings on the Funlux can I get the screen to look like the bigger one from the Zmodo unit?
The Bright circle on the one pic is the reflection from the flash on my phone in the tv screen.

Actually… I figured it out…
